How do you beat sake fireball jutsu?

the handseals for the katon gokakyuu no jutsu (fire ball jutsu) are: serpent,ram,monkey,boar,horse,tiger

now,what you have to do is focus a large amount of chackra from the chest and hold it there until it starts to burn, then generate the chackra through your mouth.

- it will take a while before anything happens, so be persistant-

hint: fire based jutsu come from the breath not with anger
